I use Opera...Though at the moment, it's only because of the search...I miss Opera 12, but currently use the latest dev (19 atm).
Without using add-ons, I can search different search engines easily, without having to select from a drop down menu like Firefox.
Want to search Wiki? 'w Star Trek' in the url bar. Amazon? 'a Star Trek'. Or easily add your own.
Opera 12 with dragonfly is so much better than Chromes/Opera 19..
I don't much like Chrome...My second browser of choice is Firefox, followed by IE11. Must admit, IE is a huge improvement. I don't actually mind it as much anymore.
I've come close to switching back to Firefox a few times lately lol
